Before Ben Affleck took over the role of Batman, The Dark Knight Rises ended with the possibility of Joseph-Gordon Levitt donning the cape when his character discovers the Batcave. While this could have laid the groundwork for a new film in the series, the Snowden actor believes it was actually the perfect conclusion.

During an interview with Cinema Blend, Gordon-Levitt was asked if he was ever interested in continuing the series and having his character John Blake become Batman. He shared that he felt it would be unnecessary since the film’s ending already revealed that Batman is more than just one man.

“I know we’re all used to the sort of Marvel movies, which are just kind of endless series,” said Gordon-Levitt. “They don’t really have a beginning, middle, and end. But I think [Christopher] Nolan very much thought of that movie as a conclusion, and there’s a theme that runs through all three of those movies that begins in the first movie, runs through the second movie, and it concludes in that moment where he says that Batman is more than a man, Batman is a symbol. And so to have another man other than Bruce Wayne kind of becoming Batman at the end of that trilogy, I think that’s the perfect ending to that story.”

In Dark Knight Rises, Gordon-Levitt stared as Blake, an idealistic cop, who assists both Bruce Wayne (Christian Bale) and Commissioner Gordon (Gary Oldman). Late in the film, it’s revealed his legal first name is Robin, a clear nod to Batman’s sidekick.

The actor will next been seen in Oliver Stone’s Snowden, which lands in theaters on Sept. 16.
